Product Description
A worn or warped gasket lets liquid bypass the filter and weakens the vacuum seal, compromising results. Fresh PTFE gaskets restore a tight seal between the funnel and support base so every drop passes through the membrane, keeping your filtration results consistent and your benchtop dry.
This listing is for catalog number 6168-4741: PTFE Gasket, Pack of 10. PTFE is chemically inert and stands up to acids, bases and organic solvents that would degrade rubber seals, and its non-stick surface helps prevent membranes from sticking. These gaskets are replacement parts for the Heathrow Scientific glass vacuum filter holder systems and are supplied in packs so spares are always on hand. LIGHT LABS ships genuine Heathrow Scientific products with knowledgeable support from our Englewood, Colorado team.
